Application filed November 8, 1907. Serial No. 401,314.

To all whom 'it may concern:

Be it known that l, JULIO OARLEsiMo, a subject of the King ot Italy, residing at Buenos Ayres, Argentina, have invented certain new and useful Improvements in Dredges, of which the following is a specification.

My invention relates to improvements in drcdges in which the material to be dredged is collected during the travel of the vessel by pushing the dredging head into the material so that the latter forms an embolus at the mouth of the head and prevents the simultaneous entrance oi' water into the suction conduit, the continued traveling of the barge to which the head is held in fixed relation and the continually forming embolus causes or assists in elevating the material in the conduit.

T he objects of my improvements are to reduce to a minimum the length of the conduit, to maintain the cutting edge oi the dredging mouth with relation to the bottom to be dredged without the use of hinges or other means, and to provide a rigid supl ort for the dredging head adapted to be readi y adjusted and cap able oil overcoming the resistance connected together by two or more telescoping sections as 9 and 10 by means of which the length of the con duit may be automatically changed.

One end of the dredging head 7 is preferably formed with an enlarged cutting mouth 7a lying in a vertical plane and said head is mounted in the lower end of the frame 3 in such manner that it may be rotated in relation to the longitudinal axis of the conduit by means oi controlling chains 11, which are connected with said head and adapted to be manipulated by any suitable means.

The discharge end section 8 is carried by a support 12 mounted in the well 2 and is provided with a horizontal portion which projects into the barge and with a vertical portion for the reception of one of the connecting telescoping sections.

To make the conduit air and water tight the several sections are provided with suitable packing rings as 13 and stui'iing-boxes as 14 as shown in Fig. 4.

lhile the trame 3 is made su'l'liciently strong and rigid to overcome all resistance and to insure the penetration ofthe dredging head into the material, additional strengthoi'fered by the material during the travel of l ening means may be provided such as brace the head through the material.

ln the accompanying drawings z-Figure 1 is a front elevation of the suction conduit and supporting frame. Fig. 2 a side elevation of the same. Fig. 3 is a horizontal section on the line M--M oi Fig. 1 and Fig. 4 an enlarged detail vertical section of the conduit.

ln said drawings 1 designates so much oi a barge or vessel su'flcient to illustrate the invention, said barge being provided with an open well 2. Mounted within said well is a rigid trussed frame 3 suspended from a derrick 4 by suitable blocks and tackle such as 5 by means of which the frame is raised and lowered. journaled in the well to engage the longitudinal members oi the frame to preventlateral play and insure an easy adjustment of the frame in the well.

The conveyer-conduit comprises a dredging head 7 and a discharge head or section S,

\ dredging chains 15 adapted to extend from the lower end oi the frame 3 and be connected to the forward part of the barge.

l claim:

1. The combination with a vessel, of a head having its mouth o ening in the direction of travel of the vesse a frame rigidly connected with the vessel carrying the head and adapted to cause the latter to penetrate the material during the travel of the vessel, and an automatically adjustable conduit connected to the head.

The combination with a vessel having a vertical well therein, of a rigid frame adjust- Anti-friction bearing rollers are ably mounted in the well, a dredging head mounted in said frame having its mouth opening in the direction of travel of the vessel, a 'hXed discharge head, and a plurality ot' telescoping sections connecting the dredging and discharge heads.

3. The combination with a vessel having a well therein, of a rigid frame movable verframe connecting the dredging and discharge tically in seid well, antifriction bearings heads. l0 journaled in the well forming lateral supports In testimony whereof I affix my signature for the frame, e dredging head mounted in in ythe presence of two witnesses.
